If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the
model in a cool place will let the wrinkles disappear. Otherwise, remove
wrinkles in covering film with a hair dryer, starting with
low temperature. You can fix the corners by using a hot iron.
Bei Sonneneinstrahlung und/oder Wärme kann die Folie erschlaffen bzw. Falten

1- Using a pencil, mark the center of the brace.
2- Trial fit the wing joiner into one of the wing panels. It should
insert smoothly up to the center line marked above.
3- Slide the other wing half onto the dihedral brace until
the wing panel meet. If the fit is over tight, it may be
necessary to lightly sand the dihedral brace.
4- Check for the correct dihedral angle.
5- Mix approximately 30 minute epoxy and apply a generous amount of epoxy into the wing joiner cavity of one wing half.
6- Coat one half of the dihedral brace with epoxy up to the center line. Install the epoxy-coated side of the dihedral brace
into the wing joiner cavity up to the center line, marking sure that the “V” of the dihedral brace is positioned correctly
7- Do the same way with the other wing half.
8- Carefully slide the wing halves together, ensuring that they are accurately aligned. Firmly press the two halves
together, allowing the excess epoxy to run out. Clear off the excess epoxy.
WARNING: Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol, only use
kerosene to keep the colour of your model not fade.

With the retract and retract servo in the retracted position, mark the position where
each of the pushrod will attach to the servo arm, a small piece of masking tape
works well for this. Cut off the excess length each rod.
Link the servo and retract gear arm with push rod. Be sure to adjust the stroke so
that the landing gear locks in both up and down position.

IMPORTANT: Flying your model at these throws will provide you with the greatest chance for successful first flights. If,after you have
become accustomed to the way the Mig-3 flies, you would like to change the throws to suit your taste that is fine. However, too much
control throw could make the model difficult to control, so remember, “more is not always better”.

Sticker
Note: Cut out the stickers and apply them in the proper area. Do not peel the backing paper off all at once.
Peel off one corner of the backing and cut off with scissors. Arrange sticker on model and when satisfied adhere the
corner without backing.
Carefully peel back the rest of the backing while at the same time adhering the rest of the sticker.
Try not to make air bubbles, if there are some, carefully puncture sticker (center of bubble) but not model surface with
the tip of the knife or sharp pin and squeeze out the air. At curves stretch sticker and apply a little heat so that no
ceases occur. Cut off the excess that is produced.
IMPORTANT: Please do not clean your model with pure alcohol, only use liquid soap with water or use glass cleaner
to clean on surface of your model to keep the colour not fade.
BEFORE FLYING CHECK EVERYTHING
Before each flight, inspect the airplane for any loose parts. Check the hinges, make sure the pushrods are still firmly
attached, and check the engine mounting bolts. In general, check everything on the plane that might possibly come
loose.
SAFETY NOTES AND WARNINGS RELATING TO MODEL AIRCRAFT POWERED BY GLOWPLUG ENGINE
Adjust the engine always from behind, but never from infront or the sides as rotating propeller may badly injure you!
Do not allow watching people to get too close to a rotating propeller.
Ensure the spinner and propeller are securely attached. Immediately disure defective propeller as well as deformed
spinners.
Be sure to keep an adequate supply of fuel in the tank. Don’t continue to fly the model until the tank is drained dry.
Never fly directly over people or fly directly towards people.
This model is highly pre-fabricated and can be built in a very short time. However, the work which you have to carry
out is important and must be done carefully. The model will only be strong and fly well if you complete your tasks
competently - so please work slowly and accurately.
